One thing I have noticed in the past few days is that in the absence of reliable, truthful information coming from any trusted authority, there seem to be increasingly hysterical reports all around the internet about what is going on. I sure can't tell with any certainty what is/might be true in some of the things I've seen, as geology and petroleum science is not my field of knowledge.
One place that does seem to have quite a few knowledgeable people with experience in the oil-drilling field is _http://www.theoildrum.com/. There are volumes of discussion, debate and observation there from people who work, or have worked in the industry, and detailed technical explanations about what is going on. It becomes clear after a little reading that there is quite a bit of science involved which most people are simply unaware of. No one there is suggesting that this is anything other than an oil well. The white stuff seen on the underwater cameras is methane hydrate which is frozen, and would be expected to be coming from a well like this, at least according to what I've read there. I don't agree with the basic peak-oil premise of the site, but I've learned quite a bit about oil drilling, and enough to understand that none of us really have all the data about what is happening.
It does seem clear that this situation is out of control and much worse than what the public is being told. And it wouldn't be a stretch to imagine the result will be increasingly chaotic on many levels in the coming weeks. As for whether it was intentional, I think that depends on how high up the chain one wants to go. Even if no humans were consciously intending this, it seems like it would fit into the 4-D STS plan quite well.
